KNIFE SHARPENER.

To al! 'wicm t may concern Re it known that I, CHARLES Cr-IrZEwEP., acitizen of the United tates, residing at Chicago, in the county of Cookand State of Illinois, have invented new and useful ln'iprovements inKnife Sharpeners, of which the following is a specification.

This invention relates to knife Sharpeners, and an object of theinvention is to provide a simple, durable knife sharpener structure bymeans of which a knife can be properly sharpened by a novice or personunskilled in the art.

More specifically, the invention comprehends the provision of a knifeSharpener which is designed so that its various parts can be constructedby means of punch presses, thereby providing a simple, inexpensiveSharpener.

Other objects of the invention will appear in the following detaileddescription taken in connection with the accompanying drawings wherein:-

Fig. 1 is a plan view of the improved knife Sharpener.

Fig. 2 is a longitudinal section through the knife Sharpener taken onthe line Q-2 of Fig. 1.

Fig. 3 is a cross section taken on the line 3 3 of Fig. 1.

Fig. 4 is an enlarged plan of the head end of the Sharpener.

Referring more particularly to the draw-- ings, the improved knifeSharpener coniprises a handle l which is constructed of a flat piece ofsheet or bar metal and is pro-r vided with an opening 2 by means ofwhich the Sharpener may be suspended or hung up. The end of the handleremote from the opening 2 is forked to provide a pair of spaced arms 3and 4 which are drilled to provide bolt or rivet receiving openings 5.Bolts 6 extend through the openings 5 and through relatively largeopenings 7 formed centrally in a pair of sharpening discs 8. Thesharpening discs 8 are Securely held in place against the arms 3 and 4by means of the bolts and the nuts 9 which are threaded upon the boltsand they are positioned so that their perimeters engage at a linebisecting the handle 1 longitudinally, as shown inv Figs. 1 and 4 of thedrawings, providing a Space between their perimeters outwardly of thehandle which converges and into which a knife is placed with the edgeengaging the perimeters of the discs after which the knife is drawnbac-k and forth with its edge engaging the perimeters of the discs tosharpen the knife. The discs 8 are made of tooled or hardened steel soas to have the proper sharpening action upon the knife.

Itis, of course, to be understood that the invention may be constructedin other manners and the parts associated in different relations and,therefore, I do not desire to be limited in any manner except as setforth in the claim hereunto appended.

Having thus described my invention what 1 claim is A knife Sharpenerincluding a handle consisting of a flat piece of sheet metal of the samethickness throughout its length, having one end forked to form divergentspaced arms, the outer ends of Said arms having transverse openingstherethrough, hardened steel discs positioned against one face of saidarms and having their periphh eries in normal contacting position withrespect to each other, said discs having central openings therethrough,the openings in said discs being of greater diameter than the openingsin the arms, bolts extending in a straightl transverse line through saidopenings whereby to mount the discs for adjustment with respect to thearms, and nuts threaded on one end of the bolts in clamping engagementwith the arms to retain the discs in adjusted positions.

In testimony whereof I affix my Signature.

CHARLES CHIZEWER.
